Alternative Name CHK2 (CHEK2 Antibody Abstract)
Background Chk2 (checkpoint kinase 2) is the mammalian homolog of the Saccharomyces cerevisiae Rad53 and is required for the DNA damage and replication checkpoints (1). In response to low-dose ionizing radiation (IR), which occurs in an ataxia telangiectasia mutated (ATM)-dependent manner, Chk2 can phosphorylate the mitosis-inducing phosphatase Cdc25C on an inhibitory site, blocking entry into mitosis, and p53 on a regulatory site, causing G1 arrest (2,3). In human tissues, Chk2 is homogeneously expressed in renewing cell populations such as epidermis or intestine, heterogeneous in conditionally renewing tissues, and absent or at low level in static tissues such as muscle or brain (4). Mutations in Chk2 inactivates DNA damage checkpoint pathway involving Chk2 in lung cancer suggesting that reduced expression of Chk2 may be responsible for the development of lung cancer (5). The Chk2-/- knockout cells are resistant to DNA damage-induced apoptosis, defective for p53 stabilization and for induction of p53-dependent transcripts such as p21 in response to gamma irradiation (6).Synonyms: CHEK-2, CHEK2, CHK-2, CHK2 checkpoint homolog, Cds1, RAD53, Serine/threonine-protein kinase Chk2
